Lotus will run an updated rear wing at the Singapore Grand Prix which is designed to improve the performance of its DRS.

The upgrade is separate to the double-DRS innovation that Lotus had been testing prior to the mid-season break, with the team having previously announced it would not be seen before the Japanese Grand Prix. However, the new rear wing is designed to improve the advantage gained when the DRS is deployed, and technical director James Allison said it will still allow the team to run a high downforce set-up in Singapore.

"We have a new floor and a new rear wing," Allison said. "The new rear wing operates at the same downforce level as our Monaco spec rear wing, but with a better DRS delta. This means that this wing has better DRS switching from its maximum drag to its reduced drag settings. We believe we've been able to produce a rear wing which is at the higher end of the downforce spectrum but still able to allow the lion's share of the DRS potential which is more difficult to achieve at high downforce levels. It will be interesting to see how it works on track."

Allison also expects Lotus to be more competitive in Singapore due to the tyre compounds that have been selected by Pirelli.

"We weren't as competitive at Monza as we have been for most of this season, but I don't think this represents the beginning of any bad trend; it just reflects something of the particular nature of Monza. In common with Spa, the tyre allocation from Pirelli was conservative on two fronts; namely the combination of a harder compound rubber than we would have anticipated and a construction which is different from that used at the other tracks we've visited.

"Combine those two factors and we weren't able to play our usual trump card, which has been better tyre management in the race. Both Monza and Spa could be comfortably completed with a one stop strategy, or even conceivably with no stops if the rules allowed it. This means we couldn't enjoy our traditional advantage. Happily the tyre allocation reverts to the previous policy from Singapore onwards."
